The compression numbers are as follows:

All Normalised:

Rotor 1: 758, 768, 768
Rotor 2: 535, 485, 535

Starter motor rpm when cold 180, and starter motor rpm 252 when hot. Car starts easily cold or hot. Once started hot on a dying battery also.

The car runs fine, pulls well and idle is rock solid, has dynode at 158 bhp at 8000 rpm will a filthy air filter, very old spark plugs, bad very worn coils and bad leads.

For some reason I do not find the compression numbers believable. In your experience is an engine like this able to start easily hot or cold at those rpm's and has no hesitation whatsoever to go to redline?

 

If it runs don't sweat it...but I would think you should start looking at saving money for a rebuild

 

It has been running great 2 years now. I changed all the bad/old parts and the car just flies. Starts the same as it did 2 years ago.

 

Some people report having zero symptoms of compression loss, yet still fail the test. Either ensure that the test was performed correctly, take it for a second opinion or do as dannobre suggests.

 

Thanks for the replies guys, I will carry on without worrying about it until I go for a trip to Athens or Rhodes some time where there are Mazda dealers, and have it checked again.
